The detection of shallow buried objects is a difficult problem in underwater archaeology and marine survey. In this paper, the existing detection techniques of shallow buried objects under water are sorted out, and it is considered that the traditional detection techniques of buried objects under water have disadvantages, and three-dimensional synthetic aperture sonar technology is more advantageous. Through the measurement of ancient shipwrecks on the seabed, this paper believes that 3D synthetic aperture sonar can effectively obtain the information of three-dimensional structure, buried depth and high-resolution image of shallow buried objects, which can realize the detection and accurate identification of shallow buried objects more effectively.
